I have 2 used Pirelli Pzero Rosso's 235/35/19. I haven't measure the tread yet, but I would estimate they are at 70%. They came with a set I purchased used for the rear tires, but I have the stock 18" front wheels. I measured the contact patch and it is 9" and the stock rear 255 Continentals were 8 1/2" or so. Eventhough these are 235 they look larger than the stock rear 255's. Had thoughts of retaining these for the rear but I have monster 295/30/19's to squeeze on. New these tires are $330 or $660 for two. I'll sell for $175 total plus shipping. I'll ship as cheaply as possible. I can post some pics later. Would trade for some stock SRT manifold's. The picture below is just an example, I'll post the real ones this week.
